CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.

CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here

  • Machine Doubling?

    First off, thanks to everyone who responded to my last post, I believe this is just another example of machine doubling, but wanted to make sure. Any info would be helpful.

    Thanks WIN_20241027_17_08_04_Pro.jpg WIN_20241027_17_07_50_Pro.jpg WIN_20241027_17_07_57_Pro.jpg WIN_20241027_17_07_54_Pro.jpg

    Hello MJammann,
    You are correct there is some MD Machine Damage Doubling but there is also Die wear or Die Fatigue Doubling. Notice it's in different directions. Roosevelt's neck or base looks very high like the metal is rolling away from the die or very hot. then the mintmark has East MD and the back of the head is west MD.
    None of this carries any value other than 0.10C but it is a nice reference coin.
    Thanks for posting.
    Eric
